Traditional automated reservoir dispatching relies solely on the regulatory capacity of hydropower resources to realize load adaptation

flood control and water-supply scheduling. Suffering from slow response speed and limited regulation accuracy

it can hardly accommodate the stochastic fluctuation characteristics of new-energy power. Energy storage systems feature technical merits including rapid charge-discharge capability

bidirectional power regulation and flexible operating-condition switching. They can complement reservoir hydropower dispatching and remedy the dynamic regulation deficiencies of conventional hydropower scheduling. On this basis

this paper analyzes the synergistic operation mechanism of automated reservoir dispatching systems with energy-storage participation

establishes an integrated architecture of hierarchical dispatching and data perception-communication

and investigates operation control strategies under steady-state and dynamic-disturbance scenarios. It aims to provide references for theoretical research and engineering applications of joint hydro-photovoltaic-energy-storage dispatching.
